Claims

[Scope of Claim for Utility Model Registration] 1. In a vehicle heating system equipped with a hot air combustion type heater using fuel as a heat source and a hot water type heater using cooling water of a driving engine as a heat source, the first set temperature and The first temperature sensor and the second temperature sensor are connected to the controller that has been set to a lower second set temperature.
input a signal from the temperature sensor, and when the temperature difference between the first temperature sensor and the first set temperature exceeds a predetermined value, both the hot air combustion type heater and the hot water type heater are operated; A heating device for a vehicle, characterized in that the controller is configured to stop the operation of the hot air combustion type heater when the signal from the second temperature sensor is higher than the second set temperature. 2. The heating device for a vehicle according to claim 1, wherein the object to be sensed by the second temperature sensor and the second set temperature are the vehicle interior air temperature. 3. The heating system for a vehicle according to claim 1, wherein the object to be sensed by the second temperature sensor and the second set temperature are cooling water for a driving engine. 4. The vehicle heating system according to claim 1, wherein the sensing target of the second temperature sensor and the second set temperature are the outlet air temperature of a hot air combustion type heater. 5. The heating device for a vehicle according to claim 1, wherein the object to be sensed by the second temperature sensor and the second set temperature are outside air temperatures. 6 A third set temperature lower than the second set temperature is provided, and when the sensing target temperature is below the third set temperature, the hot air combustion type heater is operated on "strong", and the sensing target temperature is set to the third setting. The vehicle according to any one of claims 1 to 5 of the utility model registration claim, characterized in that when the temperature exceeds a second set temperature and the temperature falls below a second set temperature, the hot air combustion type heater is operated in a "low" mode. heating equipment.
